Abstract

According to one embodiment, there is provided a disk device including a first connector, a second connector and a controller. The first connector is connectable to a host. The first connector includes a first pin that is electrically connectable to a light emitting device in the host. The second connector is connectable to the host. The second connector includes a second pin that is receivable with data from the host. The controller is communicable with predetermined information with the host via the first pin.

First claim

What is claimed is:

1. A disk device comprising:
a first connector that is connectable to a host, and includes a first pin that is electrically connectable to a light emitting device in the host;
a second connector that is connectable to the host, and includes a second pin that is receivable with data from the host; and
a controller that is communicable with predetermined information with the host via the first pin.

2. The disk device according to claim 1 ,
wherein, in a first mode, the controller performs light emission control of the light emitting device via the first pin, and in a second mode, the controller is transmittable with information regarding a state of the disk device, to the host via the first pin.

3. The disk device according to claim 2 ,
wherein, in the first mode, the controller continues light emission control of the light emitting device until a request is received, and in accordance with reception of the request, stops light emission control of the light emitting device and switches from the first mode to the second mode.

4. The disk device according to claim 3 ,
wherein the state information includes at least one of information indicating normality/abnormality of the disk device, information indicating an operation history of the disk device, and information indicating an operation environment of the disk device.

5. The disk device according to claim 3 ,
wherein, when a power of the disk device is turned off, the controller switches from the second mode to the first mode.

6. The disk device according to claim 3 ,
wherein, when a power of the disk device is turned on, the controller switches from the second mode to the first mode.

7. The disk device according to claim 2 ,
wherein the controller activates a spindle motor and performs spin-up in accordance with a level of the first pin at a time of activation of the disk device, and starts the first mode in accordance with the spin-up.

8. The disk device according to claim 3 , further comprising
a disk,
wherein, in the second mode, the controller outputs state information regarding a state of the disk device, to the first pin in accordance with the request.

9. The disk device according to claim 2 ,
wherein, in the first mode, the controller continues light emission control of the light emitting device until a duration time of the light emission control reaches a predetermined time, and in accordance with the duration time reaching the predetermined time, stops the light emission control and switches from the first mode to the second mode.

10. The disk device according to claim 9 , further comprising
a disk,
wherein, in the second mode, the controller outputs state information regarding a state of the disk device, to the first pin at a predetermined cycle.

11. The disk device according to claim 10 ,
wherein the state information includes at least one of information indicating normality/abnormality of disk device, information indicating an operation history of the disk device, and information indicating an operation environment of the disk device.

12. The disk device according to claim 9 ,
wherein, when a power of the disk device is turned off, the controller switches from the second mode to the first mode.

13. The disk device according to claim 9 ,
wherein, when a power of the disk device is turned on, the controller switches from the second mode to the first mode.

14. The disk device according to claim 1 ,
wherein the controller detects a start condition of spin-up via the first pin at a time of activation of the disk device.

15. The disk device according to claim 14 ,
wherein, if the first pin is at a first level at a time of activation of the disk device, the controller waits until a spin-up command is received, and in accordance with reception of the spin-up command, activates a spindle motor and performs spin-up.

16. The disk device according to claim 15 ,
wherein, if the first pin is at a second level at a time of activation of the disk device, the controller activates the spindle motor and performs spin-up without waiting.

17. The disk device according to claim 1 ,
wherein the first connector is a power connector, and
the second connector is a data connector.

18. The disk device according to claim 1 ,
wherein the first connector corresponds to a power connector complying with a Serial Advanced Technology Attachment (SATA) standard,
the second connector corresponds to a data connector complying with the SATA standard, and
the first pin corresponds to an eleventh pin of the power connector.

19. The disk device according to claim 1 ,
wherein the controller is communicable with the predetermined information with the host via the first pin while continuing communication via the second connector.

20. The disk device according to claim 1 ,
wherein the controller performs communication via the second connector at a first speed, and performs communication via the first pin at a second speed slower than the first speed.
